Hyaluronic Acid Is an Effective Dermal Filler for Lip Augmentation: A Meta-Analysis.

ABSTRACT: Introduction: The lips and the mouth play an indispensable role in vocalization, mastication and face aesthetics. Various noxious factors may alter and destruct the original structure, and appearance of the lips and the anatomical area surrounding the mouth. The application of hyaluronic acid (HA) may serve as a safe method for lip regeneration. Although a number of studies exist for HA effectiveness and safety, its beneficial effect is not well-established. Aim: The present meta-analysis and systematic review was performed to investigate the effectiveness of HA on lip augmentation. We also investigated the types and nature of adverse effects (AEs) of HA application. Methods: We reported our meta-analysis in accordance with the PRISMA Statement. PROSPERO protocol registration: CRD42018102899. We performed the systematic literature search in CENTRAL, Embase, and MEDLINE. Randomized controlled trials, cohort studies, case series and case reports were included. The untransformed proportion (random-effects, DerSimonian-Laird method) of responder rate to HA injection was calculated. For treatment related AEs descriptive statistics were used. Results: The systematic literature search yielded 32 eligible records for descriptive statistics and 10 records for quantitative synthesis. The results indicated that the overall estimate of responders (percentage of subjects with increased lip fullness by one point or higher) was 91% (ES = 0.91, 95% CI:0.85-0.96) 2 months after injection. The rate of responders was 74% (ES = 0.74, 95% CI:0.66-0.82) and 46% (ES = 0.46, 95% CI:0.28-0.65) after 6 and 12 months, respectively. We included 1,496 participants for estimating the event rates of AEs. The most frequent treatment-related AEs were tenderness (88.8%), injection site swelling (74.3%) and bruising (39.5%). Rare AEs included foreign body granulomas (0.6%), herpes labialis (0.6%) and angioedema (0.3%). Conclusion: Our meta-analysis revealed that lip augmentation with injectable HA is an efficient method for increasing lip fullness for at least up to 6 months after augmentation. Moreover, we found that most AEs of HA treatment were mild or moderate, but a small number of serious adverse effects were also found. In conclusion, further well-designed RCTs are still needed to make the presently available evidence stronger.

Project description:INTRODUCTION:Glans penis augmentation (GPA) using hyaluronic acid (HA) gel has been developed for treating premature ejaculation (PE) with penile hypersensitivity. The injected HA filler creates a barrier that reduces the tactile stimuli to the hypersensitive dorsal nerve. Although the HA filler is biodegradable and is believed to not cause permanent loss of sexual function, the current International Society for Sexual Medicine guideline for PE does not recommend this procedure owing to concerns regarding sexual dysfunction. AIM:To investigate the practice patterns for GPA using HA filler among Korean urologists, and to identify whether urologist experienced patient reports of sexual dysfunction post-treatment. METHODS:Between March 2016 and July 2016, a specially designed questionnaire was mailed to 86 selected Korean urologists who had used injectable materials to treat PE. MAIN OUTCOME MEASURES:The prevalence and awareness of sexual dysfunction after GPA using HA filler were evaluated. RESULTS:Overall, 56 urologists completed the survey (response rate: 69.2%), of which 36 (64.3%) had performed GPA using HA filler. They reported having performed a combined total of 4,344 such GPA procedures. Most urologists (72.7%) performed GPA using HA filler in patients who benefit from topical anesthetics. Patients with a history of failed pharmacotherapy (59.1%) and selective dorsal nerve neurotomy (45.5%) were selected for GPA using HA filler. The respondents (44.4%) encountered overall 206 (4.7%) cases of patients reports of recurrence of PE. Interestingly, only 36 (0.8%) cases of glans pain or paresthesia and no cases of erectile dysfunction post-treatment were reported. CONCLUSION:Korean urologists performed GPA using HA filler when pharmacotherapy failed or if there was a response to topical treatment. Paresthesia and hypoesthesia after GPA using HA filler are rare, and no cases of erectile dysfunction were encountered by Korean urologists. Jeong HG, Ahn ST, Kim JW, et al.
